Obsolete rows request [storage mode]

We already have -k mode, which you call -M mode.  Same thing.

But depending on memcached to return those items later is kinda dangerous.
Too much like a database.

Plus you're thinking in the 1-memcached-server world.  Have you thought
how this would work with 40 memcached servers?

You might want to look into MySQL Cluster, if you really want this done
